Alligator Free Screensaver. Photos slideshow. Alligator screensaver. This free screensaver contains many pictures of Alligator. Alligators are characterized by a wider snout than crocodiles. Both living species also tend to be darker in color, often nearly black but color is very dependent on the water. Algae-laden waters produce greener alligators; alligators from waters with a lot of tannic acid from overhanging trees are often darker (although the Chinese alligator has some light patterning.) Also, in alligators only the upper teeth can be seen with the jaws closed (in contrast to true crocodiles, in which upper and lower teeth can be seen), though many individuals bear jaw deformities which complicate this means of identification. The eyes of a large alligator will glow red and those of a smaller one will glow green when a light is shined on them. This fact can be used to find alligators in the dark. An average American alligator s weight and length is 800 lbs (360 kg) and 13 feet (4 m) long. According to the Everglades National Park website, the largest alligator ever recorded in Florida was 17 feet 5 inches long (5.3 m). The largest alligator ever recorded in Alabama measured 12 feet 8 inches (3.7 m). The largest alligator ever recorded measured 19 feet 2 inches (5.8 m) and was found on Marsh Island, Louisiana. Few of the giant specimens were weighed, but the larger ones could have exceeded a ton in weight. The Chinese Alligator is smaller, rarely exceeding 7 feet (2 m) in length.
